"Ricocheting bullet-like" chase calls. First call in cut with 4 notes, then loudest at center with 8? notes, then another distant call with 4 notes. Three males observed chasing and calling along the dense shrubby edge of a larger area with much tall grass. Two of the three frequently perched fairly closely, then quickly resumed chase with much calling thereafter, with a third less aggressive individual joining them each time. The third male, although observed landing once or twice, usually seemed to originate from an unseen perch farther away. At least two of birds were calling during the recording. On the Sandy Cruz trail approximately 75 yards in from the trail head and road at Zion's Hill. Resident.
Black-faced Grassquit (3 singing males, 1 f) were seen in the general area, with a pr observed at the exact recording location. Thin chips of these may be tainting the recording between 1-6 seconds, then again at 10.
